The problem with most iPad docks is that they position the tablet vertically. This is fine if all you're doing is playing music, but what if you wanted to watch a movie? The Belkin Thunderstorm solves that issue. Built in conjunction with Audifi, the device is more of a case than a dock. It may look discrete, but the sound it produces can fill a room with resonant audio from movies, music, or whatever else you're playing.
